    摘要: The present invention provides a system and method for recovering a precious metal from a geologic material. The system and method may include combining a geologic material containing a precious metal present in a non-bulk state with a first stage flux composition. The combination may be milled to provide a first stage mixture. The first stage mixture may be sintered for a first period of time at a first temperature and a second period of time at a second temperature. The second temperature may be greater than the first temperature. Sintering may promote the transition of a portion of the precious metal from a non-bulk state to a bulk state. A first stage sintered material may be recovered with a content of at least about 0.15 weight percent of the precious metal in the bulk state.
